Officer properly stopped Defendant, later convicted of DUI after bench trial, because her taillight cover had a chip resulting in taillight emitting a red and white light. Motor Vehicle Code requires that all motor vehicles exhibit at least two lighted tail lamps with a red light visible for at least 500 feet. Officer had reasonable suspicion to stop vehicle to investigate violation of Vehicle Code, and thus court properly denied Defendant's motion to suppress. (WRIGHT and McDADE, concurring.)
